Abstract: A data retransmission method includes configuring the quantity of code block groups in a transport block and configuring a plurality of physical resource groups; configuring the quantity of physical resources included in each of the physical resource groups according to the different quantities of code block groups; selecting the physical resources included in the physical resource group that corresponds to the initial transmission to send the transport block; determining the quantity of code block groups that were erroneously sent in the transport block according to the response; selecting one of the physical resources in one of the physical resource groups that corresponds to the retransmission to send at least one code block group that was erroneously sent according to the quantity of code block groups that were erroneously sent; and completing the retransmission only after all of the code block groups in the transport block have been successfully sent.

Abstract: The present disclosure describes methods and systems applicable to transport block communication as part of multiple access wireless communications. The methods and systems include a base station (120) that determines a first order for a first plurality of non-orthogonal multiple access (NOMA) layers (705). The base station (120) receives, from a user equipment (110), the first plurality of NOMA layers that carry the transport block (710). The base station (120) combines the first plurality of NOMA layers following the determined first order (715) and determines that decoding the transport block from the first plurality of NOMA layers has failed (720). The base station (120) then determines a second order for a second plurality of NOMA layers (725) and receives, from the user equipment (110), the second plurality of NOMA layers that carry the transport block (730).

Abstract: The present disclosure describes methods and systems applicable to multi-layer non-orthogonal multiple access (NOMA) wireless communication for repeating transmission of a transport block (TB). The methods and systems are applicable to transmitting one transport block on multiple NOMA layers, where the same transport block on the multiple NOMA layers have different redundancy versions (RVs). By combining multiple transmissions of the one transport block on the multiple NOMA layers, a base station can obtain a correctly decoded transport block and can successfully decode the data therein.
